HI. First, you will need to rule out any standard issues that will cause this. Check the internal, and external feed lines for any obstructions. Make sure that the internal lines are not frozen, or kinked. If the lines check out ok, move on to the water filter.
In most units, there will be a filter, present. These devices are set to operate on a particular time frame. If their filtering limit is met, the filter will stop filtering water, thus, not allowing the fluid to flow, at all. Make sure that the filter is up to date. If you have verified that the filter is ok, move on to the water inlet valve assembly.
The water inlet valve is located behind your refrigerator. Find the water supply line coming into the valve and turn it off at the source (typically under the sink). Disconnect the supply line. Remove the screws that secure the inlet valve in place.
The water inlet valve is connected by two wires. Label the wire placement on the water inlet valve before disconnecting the wires. The wires are connected to the terminals with slip on connectors
Firmly pull the connectors off of the terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.
Inspect the filter screen where the supply line connects. Remove any debris or deposits that may have built up using a toothbrush, or warm running water. If you cannot clear the clog, it will be necessary to replace the valve (the filter is not removable on most inlet valves).
Test the water inlet valve for continuity using a multimeter. Set the multimeter to the ohms setting X100 (if available, otherwise use the nearest ohm setting). Place a probe on each terminal. The multimeter should display a reading of 200 to 500 ohms. Close inspection of the inlet valve and especially the coil may reveal the exact ohm resistance rating to test for. If the water inlet valve does not pass this test, it should be replaced.
